`View, showing the clamping-'bars and hooks.
This invention has relation to invalid-bedsteads; and the nature of the invention consists in certain improvements in the constructiou of such bedsteads, as will be hereinafter more fully explained and claimed. 1
In the annexed drawings, A designates the head-posts, and B the foot-posts, of the bedstead, connected together by the usual head andvfoot boards and side rails; and their inner surfaces are provided with vertical grooves a a, which receive the verticallysliding blocks b b', for a purpose hereinafter to be explained. E designates a pulley-shaft, having pulleywheels e e at both ends, which is rigidly secured to the head-posts A, near their upper ends, below the braces. C, D, and F designate another shaft, similarly applied between the posts B, having -similar pulley-wheels, f. Between the mattress-bed and the Dulleysha-ft F of the foot-posts B, a winding-shaft, G, having its bearings upon the said posts B, is applied, operated by a crank-arm, g, and prevented from unwinding a cord' upon it by :means of a ratchet-wheel, g1, rigidly secured upon the said shaft, and a pawl, g2, upon the post B. H designates a sheet, which is spread and a lower plate, j', between which the ends ofthe sheet are irmly secured by means otf ring or eye screws t' i. The lower plates j of the bars J are pivoted to the slides b b.
K designates cords, which, when the windingshaft is applied upon the foot-posts of the bed, are attached, by means of hooks 7a, to the eyescrews t' upon the rod J at the head ot' the bed, passing thence upward over the pulleys e c, the pulleys fat the foot of the bed, thence downward to the windiugshaft Gr, around which they are wound, their free ends being secured by means ot hooks k thereon, which are enga-ged in the eyes i', to the rod J at the i'oot of the bed. It will be evident that a reversal of this arrangement will obtain when the winding-shaft is situated at the other end ot' the bed.
The before-mentioned horizontal transverse bars J are preferably pivoted to the slide-blocks b L; but I may rigidly secure them thereto should it prove desirable.
What l claim as new, and desire to secure by Letters Patent, is-
The combination ot' the eye-screws i t" with the sections]l j of the rods J, sheet H, and' hooks 7c It upon the ends ot' the cords K, sub- Y
